ATTACHMENT FOR WINDOW-SCREENS, STORM-SASHES, 8M).

SPECIFICATION forming part of Letters Patent No. 609,490, dated August 23, 1898.

Application filed March 31, 1898. Serial No. 676,019. (No model.)

To all 1071,0711 it may-concern.-

Be it known that I, JOSEPH T. ZISKOVSKY, a citizen of the United States, residing at Oedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Attachments for WVindow-Screens, Storm-Sashes, dac; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

The object of this invention is to provide simple and efficient means for fastening window-screens or storm window-sash in position permanently or temporarily; and the invention consists in the construction,combination, and arrangement of apparatus, as will be hereinafter fully set forth'and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a vertical section of. a window-casing in a line trans verse thereto, .witha screen-sash and stormsash in position therein. Fig. 2 is a fragmentary view in perspectiveTillustrating one of the spring-catches as applied to 'the upper corner of a half-window screen-sash. Fig. 3 is a similar view illustrating a modified form of the same as applied to one of the upper corners of the storm window-sash. Fig. 4 is a view in perspective illustrating a perforated plate which coacts with the catch above mentioned in securing the windowscreen or sash in position. Fig. 5 illustrates a modified form of the same which is more specially applicable to storm window-sash. Fig. 6 is a view in perspective showing the lower end of a Window-screen and the catches attached thereto. Fig. 7 is a similar view illustrating the lower end of a storm windowsash. Fig. 8 is a view of the catch for the lower end of the sash as seen from above. Fig. 9 is a front view of a window with my improved screen in position. Fig. 10 is a similar view of the screen detached.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A denotes an ordinary window-casing, which is provided with the usual stops and may not be particularly described.

B is a half-window screen-sash applied to the lower half of the casing. I

O is a storm window-sash, which is applied to the window-casing outside the outer slop A. To the stop A is attached a perforated plate D by suitable screws D. This plate is provided with an elongated hole or slot D and is preferably sunk into the face of the stop, so as to be flush therewith. This plate may be of the form illustrated in Fig. 4 or that illustrated in Fig. 5, in which the slot is placed near the upper end of the plate, and one side of the plate is extended at D the full width of the part of the casing to which it is attached for the better protection of the casing. against abrasion incident to the putting in and out of the screen-sash or storm window-sash, more particularly in the latter case. i

Near the upper end-of the window-screen or storm window-sash B or G is attached an elastic plate E bysuitable screws E, as clearly illustrated inFig. 2. The sash back of this plate is plowed at B to allow the spring to move backwardly a short distance at the up per end. Near the'upper end is a stud E of suitable size toenter the slot D in the "plate above described. In the case of half screensash the upper end of this spring-plate may extend a little above the sash, so as to afford a projection by Which it is sprung backwardly and disengaged from the stop-plate by means of the fingers or by inserting back of it a nail, awl, or the like. Tofacilitate this operation, this part of the spring-plate is beveled slightly at E or suitably offset.

In applying the spring-plate to a full screensash-that is to say, one extending the whole length of the window--the upper end of the plate should not extend above the upper end of the sash, necessarily, but should terminate therewith, as illustrated in Fig. 3. In the case of storm window-sash, particularly in order to give access from theinsid'e to the spring-plate, so as to disengage itfrom the stop-plate, an additional offset finger-plate E is attached to the inside of the springplate, and a suitable notch O is formed in the corner of the sash and on the inner side thereof to allow for the movement of this fingerplate, which, as will be evident, is inside both the top and side dividing-stops-A. (Shown in Fig. l and not indicated in Fig. 3.) By this means it is possible to detach the stormtrated in Fig. 8.

window from the inside, but on the outer side there is no apparent attachment at all and no practicable way by which the window could be detached by burglars or other trespassers.

The sash is fastened at the lower end by means of a suitable hook F, such as that illus- In practice this may be formed of a single piece of sheet metal stamped in the desired form and is provided with a suitable screw-hole F, by which it is secured to the bottom of the sash, as illustrated in Fig. 6. A nib F facilitates swinging the hook back and forth to engage or disengage with a pin G, driven into the windowsill A In many cases it is desirable to hold the window-screen or storm-sash partly open, in the former case to enable the'occupant of the room to drive out the few flies which will unavoidably find an entrance into a house and in the latter case for the purpose of ventilation. I therefore provide the lower ends of the sash with a brace II, which in practice is a light piece of steel or iron with a hole H at the outer end to engage with a pin G, above described, and a hole at the other end to admit the screw F which fastens the hook F in position. To give space for both hook and brace, the lower part of the sash is suitably plowed at B as illustrated in Fig. 6, this construction being more specially applicable to screen-sash placed in the inclosure framed by the stop A. In the case of storm -sash the attachment of these parts is as illustrated in Fig. 7, a saw kerf C being cut partly through the lower rail of the sash along its inner face from side to the center and of suitable width to take the hook F and brace II. The brace may be provided with a number of holes H for adjustment in the opening of the sash, as shown. It is evident also that screen-sash of half-window size may be attached inside the lower sash on the inner stops A by providing them with the stopplates D, though I have not considered it necessary to illustrate this construction, the

nature of which is so simple and evident as to require no special illustration or description.

In its practical application the device is extremely convenient, inasmuch as it allows the sash to'swing in and out, being supported at the upper rail by pivots E in the stops D at the sides. This not only admits of a partial opening of the screen for the purpose of expelling flies or otherwise, but also admits of the sash being completely inverted and doing service as a screen for the upper half of the window, which in many cases is desirable. In order to perform this function, it is of course necessary to mount the stop-plate at the vertical center of the window; but any slight variation in the distance is compensated for by the slot D which allows a limited movement of the sash up and down. A further desirable feature is the extreme neatness in appearance of the device, there being no buttons, screws, nails, or other protruding unsightly objects in connection with it, and the attaching parts being all practically invisible whether seen from the outside or inside of the house.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. InawindoW-screen attachment, the combination with a stop-plate D, provided with a suitable hole D of a spring-plate E attached near the upper corner of the sash, and provided with a projecting stud E and a sash to which said plate is attached suitably plowed behind said spring to admit of its springing back out of engagement with the stop-plate, substantially as described.

2. In an attachment for window-screens or storm window-sash, the combination with a slotted stop-plate D, provided with an elongated hole, D of a spring-plate E attached to the sash near the upper corner, and provided with a stud, E to engage the stopplate, and an ofiset finger-plate, E the sash to which said plate is attached being plowed at O to allow for the movement of the spring backwardly in disengaging, substantially as described.

3. The combination with a screen or storm window-sash of a spring-plate E having an outwardly-projecting stud, E a slotted plate D attached to the window-stop adjacent to said sash, a hook F attached in a suitable re cess in the lower rail of the sash, and a pin, G, in the Window-sill with which said hook is adapted to engage, substantially as and for the purpose set forth.

4. The combination with a window-screen or storm window-sash plowed a short distance near its upper corners, a spring-plate E provided with a stud E adapted to spring in and out in said plowed recess, a slotted plate D attached to the window-stop adjacent to said sash, and adapted for engagement with the stud of the spring-plate, a hook F pivoted to the lower rail of the sash, a pin G with which said hook may engage, and a brace II also attached to the lower sash-rail and adapted to engage with said pin, substantially as described.

5. In an attachment for storm window-sash, the combination with a sash plowed at O to allow for the spring of an attaching-plate, of a spring-plate E, provided with a stud, E and a slotted plate, D, having one of its sides, D extended out to the full width of the casing, substantially as and for the purpose set forth. 7 I
